  • 專業解析

    氮肥(Nitrogenous Fertilizer) 是指一類以提供植物所需氮素(N)為主要養分的肥料。氮是植物生長發育不可或缺的大量元素之一,是構成蛋白質、葉綠素、核酸(如DNA和RNA)、維生素和許多酶的關鍵成分。施用氮肥的主要目的是補充土壤中氮素的不足,以滿足作物對氮素的需求,從而促進植物莖葉生長、增強光合作用、提高作物産量和品質。

    核心功能與作用

    1. 促進營養生長:氮素是合成氨基酸和蛋白質的基礎,充足的氮供應能顯著促進植物的莖、葉等營養器官的快速、茂盛生長,使植株更顯濃綠健壯。
    2. 提高光合效率:氮是葉綠素分子的核心組成部分。充足的氮素能增加葉綠素含量,增強植物捕獲光能的能力,提高光合作用效率,為植物生長積累更多能量和物質。
    3. 提升産量與品質:對于谷物類作物,氮肥能增加籽粒蛋白質含量;對于葉菜類作物,能改善葉片大小、色澤和營養價值;對于經濟作物,合理的氮肥施用有助于提高目标産量(如籽粒、塊莖、纖維等)的數量和質量。

    常見類型

    根據氮素存在的化學形态和化合物性質,主要氮肥類型包括:

    1. 铵态氮肥:氮以铵離子(NH₄⁺)形式存在,如硫酸铵、氯化铵。易被土壤膠體吸附,不易流失,但在堿性土壤中可能揮發損失。
    2. 硝态氮肥:氮以硝酸根離子(NO₃⁻)形式存在,如硝酸铵、硝酸鈣。易溶于水,移動性強,易被植物吸收,但也易隨水流失。
    3. 酰胺态氮肥:主要是尿素,分子式為 CO(NH₂)₂。施入土壤後需經微生物作用轉化為铵态或硝态氮才能被植物大量吸收。含氮量高(約46%),是現代最常用的氮肥品種。
    4. 緩釋/控釋氮肥:通過特殊工藝(如包膜)控制氮素的釋放速率,使其與作物需肥規律更匹配,旨在提高利用率、減少損失和對環境的影響。

    網絡擴展資料

    "氮肥(nitrogenous fertilizer)"是含有氮元素的一類化學肥料,主要用于促進植物生長。以下是詳細解釋:

    1. 核心作用 氮元素是植物體内蛋白質、葉綠素、核酸等關鍵物質的主要成分,直接影響葉片發育、光合作用效率和作物産量。缺乏氮素會導緻葉片發黃、生長遲緩。

    2. 主要類型

    1. 使用注意事項
    1. 環境影響 全球約50%的氮肥未被植物吸收,通過硝化作用轉化為溫室氣體N₂O,或通過徑流污染水源。現代精準農業提倡通過測土配方、滴灌等技術提高利用率。

    典型施用公式(以尿素為例): $$ text{施用量} = frac{text{目标産量需氮量} - text{土壤供氮量}}{text{尿素含氮量} times text{利用率}} $$
